Amazingly, Black on White violence seems so rare that Al Sharpton and other civil rights leaders always need to pick black criminals and thugs as their favorite victims (Rodney King, Trayvon Martin, and Michael Brown), and then get embarrassed when they fail in portraying them as angelic innocent victims. Can’t they find a single law abiding Black that is victimized by a White criminal?

Justified anger gives Blacks the right to riot and loot

Blacks (and other "historically oppressed minorities") are allowed to express their "justified anger" with violence.

This is an important recognition of the cops as violent instigators; not for the first time are we watching how excessively forceful policing stokes rightful rage in a crowd. Source: Vice

Black justified anger is augmented by "Civil Rights" and Political Correctness. These don’t blame Blacks for their own misfortunes. Rather they always blame Whites, discrimination and slavery for black crime , low school performance and low black IQ. Even I would feel justified anger if I were convinced someone else was to blame for all my misfortunes.
